If you have a small car this amp sub is perfect, kenwood is a great quality, one of the top best for your buck. If you car radio has no rca outputs then just splice into the stereo's out speaker wires going to rear speakers connect to amp input. Use shielded rca cables or don't run power cable along audio wires or else you can get buzzing / interference noises. This Kenwood amplified sub had the best customer reviews on amazon vs Rockford, Pioneer, Alpine were good but too expensive.
